Our friday instant index brings us that veteran action star doing something pretty jaw dropping. But how? Here's nick watt. Reporter: First up on this week's instant index, action man jean claude van damme standing on the side mirrors of two volvo trucks, about to -- this is for real. And they are driving backwards, and the muscles from brussels nailed it in one take. Next up, a life lesson with a photographer in north carolina, playing dead with a 500 pound elk won't always get you out of trouble. And now an experiment spawned by that very viral snap of a new yorker letting another new yorker sleep on his shoulder on the subway. This guy tried it. And kept on failing. Also this week, the nba released its holiday spot. Over in norway, a spontaneous goal celebration, adrian alvarstein was born in swaziland, left on the steps of a church and adopted by a childless norwegian couple. Nice. But back on the subway, it's still no, no, no. While this little bundle is dancing on ice, the smallest patch of ice, for the first time in her life. And wait, wait, hallelujah, back on the subway, proof that many of us really are nice, kind people. That was the instant index, I'm nick watt.
